Abstract
PURPOSE The purpose of this study is to investigate the prevalence of vitreoretinal interface (VRI) disorders in patients with retinal vein occlusion (RVO) and to evaluate the impact of VRI abnormalities on the treatment outcomes of macular edema secondary to RVO using intravitreal aflibercept. METHODS Participants in this prospective study were consecutive patients with macular edema secondary to RVO, who received intravitreal aflibercept injections. At baseline, best-corrected visual acuity (BCVA) was assessed, and spectral domain-optical coherence tomography (SD-OCT) was performed to measure central subfield thickness (CST) and to evaluate the presence of VRI disorders, namely, vitreoretinal adhesion (VMA), vitreoretinal traction (VMT), epiretinal membrane (ERM), lamellar macular hole (LMH), and full-thickness macular hole (FTMH). The primary outcomes were the prevalence of various VRI disorders in patients with RVO and the impact of VRI disorders on BCVA and CST after aflibercept treatment in such patients. RESULTS At baseline, 16.1% of patients had VMA, 3.2% VMT, 18.3% ERM, and 1.1% LMH. There were a statistically significant improvement in BCVA and a decrease in CST in RVO patients over time. There was no statistically significant difference regarding BCVA and CST at baseline and until month 24 after treatment between patients with VRI disorders and those without VRI disorders. However, the mean number of injections during the follow-up period was higher in the group with VRI disorders (9.4±2.1) compared to those without VRI disorders (8.1±0.7, p=0.0002). CONCLUSIONS The prevalence of VRI disorders in patients with RVO was 16.1% for VMA, 3.2% for VMT, 18.3% for ERM, and 1.1% for LMH. VRI disorders were not found to affect the anatomical and visual outcomes after intravitreal aflibercept treatment in patients with RVO, although more intravitreal injections were needed in patients with VRI disorders.

[PMID: 37060158 DOI: 10.1111/ceo.14225] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Revised: 03/13/2023] [Accepted: 03/24/2023] [Indexed: 04/16/2023]
Abstract
BACKGROUND Central retinal vein occlusion and branch retinal vein occlusion are common causes of visual loss due to associated macular oedema. The aim of this review was to assess the effectiveness of interventions improving vision and treating macular oedema in central retinal vein occlusion and branch retinal vein occlusion. METHODS Medical search engines and clinical trial registries were systematically searched. Randomised clinical trials with ≥90 eyes and real-world outcome studies with ≥100 eyes each with ≥6 months follow-up were included. RESULTS There were 11 randomised controlled trials evaluating treatments for central retinal vein occlusion which met the inclusion criteria and 10 for branch retinal vein occlusion. There were 10 real world outcome studies of central retinal vein occlusion and 5 real world outcome studies of branch retinal vein occlusion. Meta-analysis was performed on studies that met the defined inclusion criteria. Main outcomes were change in visual acuity at 6-, 12-, 24- and 36 months by treatment. CONCLUSIONS Intravitreal anti-vascular endothelial derived growth factor is recommended as first line treatment over intravitreal corticosteroid due to its effectiveness and lower rate of ocular adverse events. Best outcomes are achieved when intravitreal treatment is started early. Macular laser may have an adjunctive role in branch retina vein occlusion but not central retinal vein occlusion.

Abstract
Objectives: To evaluate the prevalence of serous macular detachment (SMD) accompanying recurrent cystoid macular edema (CME) in patients initially treated for CME secondary to retinal vein occlusion (RVO) with accompanying SMD, and discuss the factors that affect the prevalence. Materials and Methods: We retrospectively evaluated the medical records of 71 patients with RVO-associated CME and SMD who achieved complete anatomical resolution after treatment with either a single dexamethasone implant or three loading doses of ranibizumab and developed recurrent CME during follow-up. Results: Initial treatment was a single intravitreal dexamethasone implant in 45 patients (63.4%) (Group 1) and three loading doses of intravitreal ranibizumab in 26 patients (36.6%) (Group 2). The mean time to CME recurrence was 4.7±0.8 months (range, 4-7 months) and was similar in both groups (p=0.984). At the time of CME recurrence, SMD was present in 41 patients (57.7%) and absent in 30 patients (42.3%). SMD was present in 27 (60.0%) of the 45 Group 1 patients and 14 (53.8%) of the 26 Group 2 patients (p=0.613). SMD was present in 48.8% of branch RVO and 71.4% of central RVO patients at the time of recurrence (p<0.001). Conclusion: SMD accompanied recurrent CME in only 57.7% of patients previously treated for CME and SMD and seems to be more frequent in patients with central RVO. Initial intravitreal treatment choice of either ranibizumab or dexamethasone implant did not affect the prevalence of concurrent SMD in patients with recurrent CME.

The impact of laboratory findings and optical coherence tomography biomarkers on response to intravitreal anti-VEGF treatment in patients with retinal vein occlusion. Int Ophthalmol 2022; 42:3449-3457. [PMID: 35538256 DOI: 10.1007/s10792-022-02344-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Accepted: 04/18/2022] [Indexed: 10/18/2022]
Abstract
AIMS To investigate potential laboratory and imaging biomarkers as treatment response predictors to intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents in patients with retinal vein occlusion (RVO). METHODS Participants in this prospective study were 53 patients with treatment naïve macular edema secondary to RVO, treated with intravitreal anti-VEGF agents and followed-up for 12 months. At baseline, all participants underwent best-corrected visual acuity measurement, dilated fundoscopy, optical coherence tomography and fluorescein angiography (FFA), while full blood count and biochemical analysis of various parameters was also performed. At month 12, treatment response was examined and classified as "favorable" or "non-response". Potential associations between laboratory/imaging biomarkers and treatment response were assessed. RESULTS Univariate analysis showed that "favorable" response at month 12 after initiation of anti-VEGF treatment was correlated with baseline central subfield thickness (CST) < 464 μm (p < 0.001), absence of subretinal fluid (p = 0.004), absence of hyperreflective foci (HF) (p = 0.004), intact ellipsoid zone (EZ) and external limiting membrane (ELM) (p < 0.001 and p = 0.001, respectively), absence of epiretinal membrane (ERM) (p = 0.020) and absence of macular ischemia on FFA (p < 0.001), while increased monocytes-to-lymphocytes ratio was also associated with "favorable" treatment response (p = 0.010). All other laboratory parameters did not reach statistical significance. However, at the multivariate analysis, EZ and ELM status, HF, macular ischemia and monocytes-to-lymphocytes ratio were found to be independent predictors of treatment response. CONCLUSIONS Intact EZ and ELM, absence of HF, absence of macular ischemia and increased monocytes-to-lymphocytes ratio at baseline can predict "favorable" treatment response in patients with treatment naïve macular edema secondary to RVO.

Abstract
This prospective comparative case series aims to compare best-corrected visual acuity (BCVA), retinal microvasculature, and retinal structural changes in patients treated with either ranibizumab or aflibercept for macular edema (ME) secondary to treatment-naïve branch retinal vein occlusion (BRVO) by optical coherence tomography angiography (OCTA). Ten patients were enrolled with macular capillary density of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) and foveal avascular zone (FAZ) measured in both eyes before and after treatment. Final central retinal thickness and BCVA improved significantly (p < 0.05), and densities of SCP and DCP of BRVO sectors were significantly lower at baseline than fellow eye counterparts and remained persistently lower during treatment, particularly in the aflibercept group (p < 0.05). SCP density, DCP density of both BRVO sectors (p = 0.0001, p < 0.0001), and non-BRVO sectors (p < 0.0001, p < 0.0001) were significantly correlated with final BCVA for diseased eyes. Using multivariate general linear model analysis, and including OCTA parameters only, but not all of the available clinical data, DCP density of BRVO sectors in both eyes was the most predictive factor for final visual outcome (probability p < 0.0001). OCTA offered further qualitative and quantitative evaluation of treatment-naïve BRVO. Judging by OCTA parameters, not only in the diseased eye but also in the fellow eye, DCP density of BRVO sectors was the most predictive factor of final visual outcome.

Abstract
Macular edema (ME) is associated with various conditions; however, the main causes of ME are retinal vein occlusion (RVO) and diabetes. Laser photocoagulation, formerly the gold standard for the treatment of ME, has been replaced by anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections. Despite its efficiency, this treatment requires frequent injections to preserve the outcomes of anti-VEGF therapy, and as many patients do not sufficiently respond to the treatment, ME is typically a chronic condition that can lead to permanent visual impairment. Generalized recommendations for the treatment of ME are lacking, which highlights the importance of reviewing treatment approaches, including recent anti-VEGFs, intravitreal steroid implants, and subthreshold micropulse lasers. We reviewed relevant studies, emphasizing the articles published between 2019 and 2021 and using the following keywords: macular edema, diabetic macular edema, retinal vein occlusion, laser photocoagulation, anti-VEGF, and intravitreal injections. Our results revealed that a combination of different treatment methods may be beneficial in resistant cases. Additionally, artificial intelligence (AI) is likely to help select the best treatment option for patients in the near future.

Abstract
Aflibercept is a fully human recombinant fusion protein that includes the second domain of human VEGF receptor 1 and the third domain of human VEGF receptor 2. Despite the important role played by VEGF in maintaining the physiological condition of the retina under normal conditions, dysregulation of VEGF can result in pathological alterations including hyperpermeability of the retinal capillaries and migration and proliferation of retinal endothelial cells. Over the years, a number of studies have evaluated the use of intravitreal aflibercept in different retinal diseases. In this review, we aim to summarize the scientific evidence and recommendations for use of intravitreal aflibercept in neovascular age-related macular degeneration, diabetic macular oedema, macular oedema associated with retinal vein occlusion, and myopic choroidal neovascularization.

Abstract
Introduction To assess the safety profile of the intravitreal ranibizumab biosimilar molecule, Razumab® (Intas Pharmaceuticals, Ahmedabad, India) in chorioretinal disorders under real-world conditions. Methods This was a multicenter, retrospective chart review which included patients from 15 centers receiving intravitreal Razumab (IVRz) injections from 2016 to 2020. Patient demographics, ocular examination data, and detailed safety information regarding serious adverse events (SAE) or serious adverse drug reactions (sADR), and non-serious AEs (nsAE) or non-serious ADRs (nsADR) occurring within 1 month of IVRz injections were compiled. Results A total of 6404 eyes of 6404 patients received 9406 IVRz injections [mean (± SD) = 1.49 (± 0.63)] during 4.25 years. Adverse events were reported after 1978 injections (21.03%): 64.16% nsAE, 32.96% nsADR, 2.37% sADR, and 0.51% SAE. The most frequent adverse events were subconjunctival hemorrhage (8.2% of total injections), transient blurring of vision (6.5% of total injections), and mild ocular pain (5.27% of total injections). Serious ocular (31 cases with retinal pigment epithelial tears [0.33%], two cases of non-infectious vitritis [0.02%], and one case of endophthalmitis [0.01%]) and systemic (seven patients with non-fatal myocardial infarction [0.12%] and six patients with non-fatal cerebrovascular accident [0.09%]) adverse events were infrequent. Conclusion The study reports the largest pooled safety data on IVRz use in a real-world scenario. The results did not raise any new ocular or systemic safety concerns for the biosimilar agent, with the incidence and spectrum of adverse reactions similar to those reported with other anti-vascular endothelial growth factor (anti-VEGF) drugs. The real-world evidence suggests that IVRz is a safe anti-VEGF agent in the management of chorioretinal disorders.

The randomized ZIPANGU trial of ranibizumab and adjunct laser for macular edema following branch retinal vein occlusion in treatment-naïve patients. Sci Rep 2021; 11:551. [PMID: 33436683 PMCID: PMC7804316 DOI: 10.1038/s41598-020-79051-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 12/04/2020] [Indexed: 11/09/2022] Open
Abstract
The ZIPANGU study assessed the efficacy and safety of ranibizumab as a one loading dose + pro re nata (one + PRN) regimen with/without focal/grid laser among treatment-naïve patients suffering from macular edema (ME) following branch retinal vein occlusion (BRVO). ZIPANGU was a phase IV, prospective, randomized, open-label, active-controlled, 12-month, two-arm, multicenter study. Treatment-naïve patients with visual impairment (19–73 letters) caused by ME, defined as central subfield thickness (CSFT) > 300 µm, due to BRVO were randomly assigned to ranibizumab monotherapy (n = 29) or combination therapy (ranibizumab + focal/grid short-pulse laser, n = 30). The primary endpoint was the number of ranibizumab injections. Secondary endpoints were mean changes in best-corrected visual acuity (BCVA) and CSFT, and safety. There were no statistically significant differences in the mean number of ranibizumab injections between monotherapy (4.3 injections) vs. combination (4.1 injections) therapy, or in CSFT. BCVA improvement in the monotherapy arm (22.0 letters) was better than the combination therapy arm (15.0 letters) (p = 0.035). Overall, both regimens appeared to be safe and well tolerated. One + PRN ranibizumab is safe and efficacious in treatment-naïve patients with ME secondary to BRVO. A conjunctive laser treatment did not lead to better functional outcomes or fewer ranibizumab injections.

Abstract
PURPOSE To evaluate macular thickness fluctuations in patients with retinal vein occlusions (RVOs) treated with anti-vascular endothelial growth factor (VEGF) agents and to assess whether patients with larger fluctuations have poorer visual outcomes. DESIGN Retrospective cohort study. PARTICIPANTS Treatment-naive patients with RVO. METHODS Central subfield thickness (CST), cube volume (CV), and cube average thickness (CAT) were collected from OCT images obtained at baseline and 3, 6, 9, and 12 months, and standard deviations (SDs) across 12 months were calculated. Mixed-effects regression was performed to examine the relationship between macular thickness SD and 12-month visual acuity (VA). Standard multiple regression was performed to identify predictors of macular thickness SD. MAIN OUTCOME MEASURES Standard deviations across 12 months for CST, CV, and CAT and VA at 12 months. RESULTS One hundred thirty-four eyes, including 71 with branch RVO (BRVO) and 63 with central RVO (CRVO), were evaluated. Mean baseline and 12-month CST were 488.6 ± 165.0 μm and 334.3 ± 131.9 μm (change, -154.3 ± 210.2 μm; P < 0.001), with CST SD of 114.1 ± 77.0 μm. Baseline and 12-month VA were 52.8 ± 20.9 letters and 65.9 ± 17.3 letters (change, +13.1 ± 20.3 letters; P < 0.001). Central subfield thickness SD was a significant negative predictor of 12-month VA (-5.21 letters/100 μm; 95% confidence interval [CI], -10.21 to -0.22 letters/100 μm; P = 0.041) when adjusting for baseline factors and injections. Baseline CST and number of injections were not predictive (P ≥ 0.101). Stratification by CST SD demonstrated a 10-letter difference in 12-month VA between the first and fourth quartiles. Baseline CST and RVO diagnosis were the only significant predictors of CST SD (CRVO vs. BRVO: +34.64 μm/100 μm [95% CI, 29.33-39.94 μm/100 μm; P < 0.001] and +22.13 μm/100 μm [95% CI, 4.81-39.44 μm/100 μm; P = 0.013]). Associations using CV and CAT were similar. CONCLUSIONS Larger macular thickness fluctuations are associated with poorer visual outcomes in patients with RVO treated with anti-VEGF agents. Macular thickness fluctuations, in addition to absolute macular thickness, may be an important prognostic biomarker in these patients.
